    What's the Least Common Multiple (LCM) of 54 and 126?

    Answer

    LCM of 54 and 126 is
    378

    (Three hundred seventy-eight)

    Finding LCM for 54 and 126 using GCF of these numbers

    The first method to find LCM for numbers 54 and 126 is to find Greatest Common Factor (GCF) of these numbers. Here's the formula:

    LCM = (Number1 × Number2) ÷ GCF

    GCF of numbers 54 and 126 is 18, so

    LCM = (54 × 126) ÷ 18

    LCM = 6,804 ÷ 18

    LCM = 378

    Finding LCM for 54 and 126 by Listing Multiples

    The second method to find LCM for numbers 54 and 126 is to list out the common multiples for both numbers and pick the first one that matches:

    Multiples of 54: 54, 108, 162, 216, 270, 324, 378, 432, 486

    Multiples of 126: 126, 252, 378, 504, 630

    So the LCM for 54 and 126 is 378

    Finding LCM for 54 and 126 by Prime Factorization

    Another method to find LCM for numbers 54 and 126 is to list all Prime Factors for both numbers and multiply the highest exponent prime factors:

    All Prime Factors of 54: 2, 3, 3, 3 (exponent form: 21, 33)

    All Prime Factors of 126: 2, 3, 3, 7 (exponent form: 21, 32, 71)

    21 × 33 × 71 = 378
